#AceHealthReport – Oct.30: Vaping aerosols contain thousands of unknown chemicals and substances not disclosed by manufacturers, including industrial chemicals and caffeine, Johns Hopkins University researchers found…..
#AceHealthDesk says according to BBC Radio 4 today NHS is being asked to provide E-cigarettes as a way to stop smoking but Johns Hopkins researchers find thousands of unknown chemicals in electronic cigarettes …
BBC Health says that E-cigarettes could soon be prescribed on the NHS in England to help people stop smoking tobacco products: The Medicines and Healthcare Products Regulatory Agency is inviting manufacturers to submit goods for approval to be prescribed: It could mean England becomes the first country in the world to prescribe e-cigarettes as a medical product

John Hopkins Research Report:
The study is the first to apply to vaping liquids and aerosols an advanced fingerprinting technique used to identify chemicals in food and wastewater. The results, just published in the journal Chemical Research in Toxicology , suggest people who vape are using a product whose risks have yet to be fully determined and could be exposing themselves to chemicals with adverse health effects.”I have a problem with how vaping is being marketed as more healthy than smoking cigarettes. In my opinion we are just not at the point when we can really say that.”Assistant professor, School of Engineering
“Existing research that compared e-cigarettes with normal cigarettes found that cigarette contaminants are much lower in e-cigarettes. The problem is that e-cigarette aerosols contain other completely uncharacterized chemicals that might have health risks that we don’t yet know about,” said senior author Carsten Prasse, an assistant professor of environmental health and engineering at the Whiting School of Engineering and the Bloomberg School of Public Health. “More and more young people are using these e-cigarettes and they need to know what they’re being exposed to.”
Previous studies of e-cigarettes have looked specifically for evidence of the hazardous chemicals found in traditional cigarettes. But here the researchers performed a nontargeted analysis to explore the full range of chemicals both in the vaping liquid and the aerosols.
Prasse and his team were the first researchers to test vape samples with chromatography/high-resolution mass spectrometry, a chemical fingerprinting technique more commonly used to identify organic compounds in wastewater, food, and blood. Although it’s possible to buy vaping products in hundreds of flavors, for consistency they tested only tobacco-flavored liquids sold by four popular brands—Mi-Salt, Vuse, Juul, and Blu. They found thousands of unknown chemicals in the liquid, and the number of compounds increased significantly in the aerosol. Furthermore, they detected condensed hydrocarbon-like compounds, typically associated with combustion, which manufacturers say is not happening during vaping. In traditional cigarettes, the condensed hydrocarbons generated during combustion are toxic.
“One of the main ways electronic cigarettes have been marketed is that they operate at temperatures below combustion, which would make them safer than traditional smoking,” said lead author Mina Tehrani, a postdoctoral fellow in the School of Public Health. “Our study shows that this novel fingerprinting approach can be applied to assess whether combustion-like processes are going on.”
The team found nearly 2,000 chemicals, the vast majority of which are unidentified. Of those the team could identify, six substances were potentially harmful, including three chemicals never previously found in e-cigarettes. Tehrani was particularly surprised to find the stimulant caffeine in two of the four products. Caffeine has previously been detected in e-cigarettes but only in the caffeine-oriented flavors like coffee and chocolate.
“That might be giving smokers an extra kick that is not disclosed,” she said. “We wonder if they are adding it intentionally.”

Besides caffeine, the team found three industrial chemicals, a pesticide, and two flavorings linked with possible toxic effects and respiratory irritation.
Prasse said he became interested in studying vaping products after his cousin, a former smoker, started vaping, insisting it was healthy. He plans to send that cousin this paper.
“People just need to know that they’re inhaling a very complex mixture of chemicals when they vape. And for a lot of these compounds we have no idea what they actually are,” Prasse said. “I have a problem with how vaping is being marketed as more healthy than smoking cigarettes. In my opinion we are just not at the point when we can really say that.”
Co-author Ana M. Rule, an expert in metals exposures from vaping with the Johns Hopkins Bloomberg School of Public Health, says many young people who vape never smoked—so they aren’t making a healthier choice, only starting out with a risky one.
“There are millions of middle school and high school students vaping that would not otherwise think of smoking,” she says. “For them there is no risk reduction, only increased risk.”
Authors also include Matthew N. Newmeyer, a postdoctoral fellow at the Johns Hopkins Bloomberg School of Public Health. The work was supported by grants from the National Institute of Environmental Health Sciences, the National Center for Advancing Translational Sciences, and NIH Roadmap for Medical Research.
